' SPECIFICATION formingpart of Letters Patent, No. 276,526, dated April 24, 1883.

Application filed February 17, 1823. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. DIXON, of Newburg, county of Orange, State of New York, and a citizen of the United States, have invented an Improved Steam-Condensing Apparatus, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming partof this specification. Y

My invention relates to an apparatus for condensing live or exhaust steam, particularly for the purpose of making distilled or fresh water; and my invention consists in a steamcondenser composed of the several specific parts, constructed, placed relatively to each other, and combined to operate substantially as hereinafter particularly set forth.

Figure 1 is a vertical central sectional view of a condenserembodying my invention. Fig. 2 is a cross-section on the line 3 y, Fig.1; and Fig. 3 is a cross-section on the line as m, Fig. 1.

My condenser is composed of five principal and distinct parts-namely, three cylinders concentrically arranged, a base-plate, and a head'sheet or top-and these parts are put together and combined to constitute the condenser, as hereinafter particularly set forth.

A is the exterior cylinder. B is the innermost cylinder, and O is the cylinder intermediate A and B. D is the base-plate, and E is the head-sheet or top plate of the apparatus. The cylinder A has the greatest diameter, as shown, and is mounted on the base-plate D, towhich it may be bolted, as shown; and it has a core or overflow-conduit formed on one side of it, as shown at a, with a dischargeopening at a into said conduit, at or near the bottom of said cylinder, and said conduit hav in g an egress-port at 0. near the top of said cylinder, as shown. Within said cylinder A, and concentric to the same, is placed the cylinder O, mounted on the base D by means of bolts passing through flange c, and arranged to inclose and constitute a space or chamber be tween it and eylinder A, and extending upward toward but not to the same height as the top line of cylinder A. B, the interior cylinder, is arranged concentrically within 0, so as to constitute a space or chamber-between it and O, and it is suspended within 0 by means of a top edge flange, Z), lapped to a flange, c,

on upper edge of O. The lower end of B is formed with a bottom plate or bead, b, as

shown, and this lower end extends downward toward but not to the line of the bottom edges of cylinders A and 0, thus constituting a space or chamber between the lower face of said end I) a-ndnpper face of base-plate D, as shown. In this plate I) of B are set the tubes b opening through said plate, as shown; and said tubes extend thence upwardly longitudinally of said cylinder 13, to and through the headsheet or top E. This headsheet E is secured in place by bolts passing through its rim and a flange, a on upper edge of A. The tubes may be expanded,or maybe screwed into their seats. An outlet-pipe, m, with a wide mouth to inclose the open upper ends-of the tubes, is bolted upon the top of the head-sheet E, as shown. The steam-inlet pipe is seen at F, passing through cylinder A, near the top of the apparatus, where a stuffing-box,f, may be provided,and extcndingthroughUandopening into the space or chamber between B and U, as shown. The condensingwater inlet is at G, passing up through base-plate D and into cylinder B, through the bottom 1) thereof, the condensing-water outlet being at a a, as heretofore described. Upon the under side of baseplate D, and opening through the same, is the conduit for the water of the condensed steam.

It is evident that the three cylinders, the base-plate, and head-sheet may all be made of cast metal in an inexpensive manner, the cylinder A having the core a a cast with it, the cylinder B having its bottom b cast with it, and the base-plate D having the conduit H cast on it, as shown, and that the several parts, by means of their flanges and bolts, as described, may be readily put together and combined to constitute the condenser, the tubes 1) being introduced as described.

The steam enters at F, and passes through and fills the spaces or chambers marked 8, and thence through the tubes b while the cold condensing-water entering'at Gr fills the cylinder B around the tubes, rises and flows over the top edge of B, and thence falls into and fills the space between A and 0, thus circulating through all the spaces and chambers marked 20, and finally passing out at a to conduit. a, and thence out at a. The steam as it condenses falls upon the base-plate D, and the water runs out through H, while the steam which fails to condense escapes at m;

By means of my apparatus the water of the condensed steam is kept free from impurities, such impurities being carried off at m with the uncondensed steam, while at the same time the structure of the apparatus secures a large surface for condensation. When it is desired, for any reason, to examine the interior of the apparatus, or to take the apparatus apart, it may be done much more readily, owing to the simplicity of its structure, than in condensers as usually constructed.

What 1 claim as new, and desire to secure by Letters Patent, is-

A steam-condensing apparatus composed of pose described. 1 CHAS. A. DIXON.
